ALFRED C. DAVIS, OF G-AFFNEY, SOUTH CAROLINA.

WASHING Macrame.

Application filed November 15, 1222. Serial No. 601,345.

To all whom it may concern:

Be it known that I, ALFRED C. DAVIS, a

citizen of the United States, residing at Gaffney, in the county of Cherokee and State of South Carolina, have invented a new and useful lVashing Machine, of which the following is a specification.

The device forming the subject matter of this application is a washing machine, and the invention aims to provide novel means whereby, through the instriunentality of a plunger mounted to oscillate in an orbit water, steam and air will be forced through the clothes to effect a cleaning thereof, novel means being provided whereby a pair of such plunger-s may have alternating oscillation, one of the plungers being adapted to move within the curve of the body of the machine, and the construction of the device being such that the clothes Will not be dragged back in the body of the machine when the plungers are retracted.

VVit-h the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, Within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made Without departing from the spirit of the invention.

In the. accompanying drawings Figure 1 shows in longitudinal section, a

device constructed in accordance with theinvention; Figure 2 is a cross section taken through one of the plungers and illustrating the construction of both of them; Figure 3 is a section on the line 3-3 of Figure 1; Figure 4 is a fragmental horizontal section.

The machine comprises a casing or frame 1 embodying a back 2, a. front 3 of less height than the back, ends 4 and a bottom 5, the ends 4 being reduced in width at their upper ends to form a correspondingly reduced upper compartment 6. A tubular body extends between the ends, 4 and is made up of an arcuate front member 7 and an arcuate rear member 8, spaced to form an upper opening 9 and a lower opening 10 in the body of the machine. The members 7 and 8 of the body of the machine have longitudinal corrugations comprising radial portions 12 and circumferential portions 14,

the corrugations on the member 7 being so arranged that when the clothes are moved in the direction of the arrow in Figure .3, the clothes will be prevented from moving downwardly and backwardly, the corrugations on the member 8 being so arranged that they will prevent the clothes from moving upwardly and backwardly. Openings 15 are fashioned in the radial portions 12 of the corrugations, and whenwater passes through the openings 15' from, the casing 1 into the tubular body, the water Will be discharged into the. body circumferentially thereof and aid in moving the clothes correspondingly. Access is had to the body of the machine by means of a lid 16 hinged at 17 to the member 7, portions of the ends 4 and of the front 3 forming an apron 22 serving to return to the body of the machine, water which may find its way above the lid 16. The front Wall 18 of the upper compartment 6 is hingedly mounted as at 19,and may be openedwhen desired. The compartment 6 is closed at its upper end-by a top 20 hinged at 21 to the back 2. A pocket 28 is carried by the back 2 and in the back there are openings 29 communicating with the pocket and With the interior of the casing 1. The pocket 28 and the openings 29 form means whereby water may be introduced into the casing 1, and through the openings 29, the steam may escape. One end 4 of the casing 1 has a drain "cock 23 through which water may be drawn off The casing 1 carries a frame 27 including lower bars 24 and upper bars 25 which are connected as indicated at 26, the bars 24 and 25 serving to reinforce the casing and forming a place of mounting for one of the plungers hereinafter described. The frame 27 may be used to support a motor (not shown) should it be desired to operate the machine by means of a motor mounted thereon.

The member 8 of the body has ends 30 provided with flanges 32 connected to the ends 4 of the casing 1 and spaced therefrom, as shown in Figure 4, to receive arms 33 carrying an arcuate hollow plunger 34, the arms being mounted on pivot members 31 carried by the parts 30, 4 and 24. At its forward end, the plunger 34 is open, but is v through the clothes.

guarded by a screen 35. The rear end of the plunger 34 carries a valve 36 adapted to close when the plunger moves in the direo tion of the arrow in Figure 3, and to'open when the plunger moves in opposite direction. Pitmans 37 are connected pivotally with the arms 33 of the .plungerfit and are assembled with cranks 38 on a shaft 39 lo cated in the compartment 6 and journaled bearings on the ends l of the casing 1. Although the shaft 39 is shown as rotated by a pulley 40, any other suitable means may be supplied for operating the shaft, by hand orotherwise. lheshaft 39 has an intermediate crank l connected by a ipi-tman 42 with anarcuate :plunger iieonst ructed like the iplimg'er 34, the arms 4140f the Eplunger 48 being mounted :pivotally, as a'te5, on the back 2. The cranks 41 and '38 are set degrees apart, and it willbe obvious that when. the iplunger 3% is advanced, the plunger 47 "will beretracted; and when the plunger 47 is advanced, the plunger will be retracted, the plunger E l operating through the'opening 10 in the body of the machine, the plunger 1-7 operating in the opening 9 of the body of the machine, the plunger 34 being mounted at-3'l tomove in'an'are which is not -'c-0 incident with the'eurve otthe members 7 and 8 of the bod-y. The plungers, coaetingwith the corrugations on the body, exert 'a rubbing action on the clothes, and the plu'ngers, further tend to force the water When the 1i lungers move rearwardly, taking" the plunger 34 of Figure '2 as typical, the valve 36 'willO e'n, andthi's va-lve is'o'itsueh size that the plunger will 'fill readily, an'd any'air which-may have been trapped in the plunger will find a ready exit.

I claim zy 1. l-n a washing machine, a tubularbody having openin gs, arcuate plungers, means for mounting the plungers for movement through the openings, and means 'for retraoting one plunger whilst the other plun- ,ger is being advanced, the body being provided, on its opposite sides, with corrugatio'ns, the torrhgations on both body comprising substantially tions, the corri'tgations on one radial por- SlClEE of the body'eoinp'rising @p'o'rtions whiehslantdownwardly and ou rdly, an d the corrugations on the "other side of the body comprising portions which slant downwardly and nwardly.

2. In a washing machine, =a casing and a tubular body positioned in the=casing, the body buying an opening in its bottom and provldetl with an opening in its top; an arcuate plunger; means for mounting said sides of the er for movement through the 'bottoin
